Little Endian to Big Endian

Code

#include <stdio.h>
#include <stdint.h>
typedef union{
    uint32_t val ;
    uint8_t bytes[4];
    
}U_V;

uint32_t convert_endian(uint32_t value) {
    // Write logic to swap bytes
    U_V s;
    s.val = value;
    uint8_t ram = 0;
    ram = s.bytes[3];
    s.bytes[3] = s.bytes[0];
    s.bytes[0] = ram;
    ram = s.bytes[1];
    s.bytes[1] = s.bytes[2];
    s.bytes[2] = ram;
    return s.val; 
} 

int main() {
    uint32_t val;
    scanf("%u", &val);
    printf("%u", convert_endian(val));
    return 0;
}
